<Gear box oil quantity>
1) Check the quantity of oil in the gearbox immediately
after tilting back the machine head.
When the machine head is left for long periods in the
tilted-back position, the amount of oil in the felt inside
the gearbox drops and more oil overflows from (a),
so that it becomes impossible to measure the actual
oil level accurately.
2) The amount of oil which overflows from (a) will very
depending on the angle at the machine head is tilted
back at.
Tilt back the machine head while the head rest (2) is
installed in the correct position.
3) If you add too much oil, oil will leak from the air holes
during operation, so after adding oil, wait until oil
stops overflowing from (a), and then replace the cap.
<Checking the oil quantity>
1) 15 ml of lubricating oil is added to the gearbox at the
time of shipment from the factory.
2) If oil overflows from (a) in the situation shown in the
illustration at left, add lubricating oil via hole (b).
